The BlueStream HCS can be controlled to minimize overall utility costs, insuring the cost of the water saved is greater than the cost of the additional fan and pump energy of the TSC unit. The annual operating cost of the system will thus be lower than what would have been possible with the cooling tower only system.

Key Features

•Nointermediatefluidpumprequired• Uses natural circulation of refrigerant• No need for antifreeze•Freezeprotectionachievedbycontrollingrefrigerantflow,

evaporator insulation, and evaporator heaters• Low waterside pressure drop to minimize pumping energy• Cleanable heat exchanger• Enables direct contact with open cooling water • Control system modes: • Minimum operating cost mode provides a balance between water and energy use • Maximum water saving mode

The BlueStream Hybrid Cooling System (HCS) is an advanced coolingsystemwhichuniquelyandcosteffectivelycombinesand integrates the control of an innovative dry heat rejection device, the thermosyphon cooler (TSC), with a conventional evaporative wet heat rejection device, an open cooling tower.

Thisnewheatrejectionsystem,acombinationofequipmentandcontrols,enablessignificantannualwatersavingstobeachieved in comparison with traditional “all evaporative” heat rejection systems while maintaining the maximum peak processoutputandenergyefficiencyonthehottestsummerdays. The BlueStream HCS embraces the “smart use of water”, using evaporative cooling when it is most advantageous and then saving water and modulating towards increased dry sensiblecoolingasprocessrequirementsandambientweatherconditions permit.

Innovative fan control strategies for both the dry and evaporative heat rejection devices assure the most economical balance between water savings and parasitic fan energy.

BlueStream Hybrid Cooling System Applications

Any heat rejection applications which have traditionally made use of cooling towers can be considered as viable candidate applications for the BlueStream HCS.

These include:

• Process Cooling • Data Centers• HVAC Applications with Water Cooled Chillers• Power Generation

The BlueStream HCS can be applied in new facilities or appliedasaretrofitsolutionforexistingfacilities.Inretrofitapplications on existing cooling tower systems, the existing cooling towers can be retained as the evaporative heat rejection portion of the BlueStream HCS solution.

The BlueStream HCS can typically drive annual water consumption savings of between 30% and 80% in comparison to a traditional “all evaporative” open cooling tower system. Key variableswhichwill impact application specificwatersavingswillincludeannualloadprofiles,processtemperatures,weatherconditions,andthequantityofTSCunitsinstalled.

Thermosyphon Cooler (TSC)

The thermosyphon cooler (TSC) is the heart of the BlueStream HCS. The TSC unit is a packaged dry heat rejection device supplied with piping, valves, controls, and instrumentation. The unit is also supplied with an enclosed VFD drive for powering the fans.

A Quantum™ HD local control panel, provides the controls and logic for operating the unit and will act as an integration point for the site control system. The TSC employs a naturally recirculating refrigerant loop to convey heat from its evaporator to its air cooled condenser.

TheuniquedesignoftheTSCallowsopencoolingwatertobecooled directly by the easily cleaned, low water pressure drop TSC evaporator without risk of bursting tubes in sub-freezing ambient conditions. Separating the water to refrigerant heat transfer in the TSC evaporator from the refrigerant to air heat transfer in the TSC condenser allows the design and metallurgy of each device to be optimized for its specificpurpose.

The TSC can also be applied directly in a primary cooling loop as a dry waterside economizer.

The evaporatorisatubeandshellstylefloodedevaporatorwith the refrigerant on the shell side, and the water on the tube side. It is constructed, tested, and stamped in accordance with applicable sections of ASME pressure vessel code.

Theevaporatorisprovidedwithventanddrainfittings,andis insulated with heaters controlled for freeze protection. It has a very low water pressure drop to minimize the pump energy. Copper tube material is standard while other tube materials are optional. In standard two pass arrangement, thewaterinletandoutletconnectionsarefittedwith6”150#classflanges.

The condenserisanaircooledsinglepasstube-fincondensersupplied with an enclosed VFD drive for powering the fans and fan speed control. The coils are internally enhanced, seamless copper tubes, mechanically expanded into aluminum alloyfinswithfullheightcollars.Itconsistsoffourcondensingcoil banks in two V-shaped arrangements.

The power for the unit is provided through a single 460V/3PH/60HZpowerconnectionlocatedintheVFDpanel.

Control: The factory supplied Quantum HD local control panelisNEMA4ratedandbuilttotheUL-508Astandard.Itprovides the controls and logic for operating the unit and will act as an integration point for the site control system. The Quantum HD panel is installed on the lead TSC in each group. OneQuantumHDcontrolpanelsupportsupto16TSCunitsinagroup.APLCcontroloptionisalsoavailableuponrequest.

It is factory wired with all the factory installed safety, operating, and monitoring devices including control of packaged valve, heaters, fan motors and their speed, water inlet and outlet temperatures, ambient dry bulb temperature and relative humidity sensors. Field installed sensors and control signals are wired (by others) to the Quantum HD control panel. Communication between multiple units uses ModbusprotocolviaRS-485,wiredbyothers.

Threefield-selectableserialcommunicationportsallowyouto choose froma combination of RS-422 or RS-485 portconfigurationsforexternalcommunicationsusingMODBUSASCII, MODBUS RTU, or Allen-Bradley DF1 protocols.Additionally, an Ethernet port allows Ethernet and Internet communications using MODBUS TCP, Allen-Bradley Ethernet I/P,orHTTPprotocols.

Operating Modes

The control logic provides two main operating modes:

• Minimum operating cost mode• Maximum water saving mode

With the minimum operating cost mode, the system automatically balances the energy and water uses to yield the lowest system operating cost. With the maximum water saving mode, the system will use the least amount of water by maximizing the dry heat rejection operation.
